Description

Technical Field

[0001] The utility model relates to the technical field of dressings, and more specifically to an anti-adhesion dressing shearing device. Background Art

[0002] Dressing refers to auxiliary materials used in addition to the main ingredients of an item. In the medical field, it specifically refers to materials used to cover sores, wounds or other lesions. An important function of modern wound dressings is to replace the important functions of damaged skin and continue to act until the wound heals and the skin lesions heal. They can resist mechanical factors, pollution and chemical stimulation, prevent secondary infection, prevent dryness and loss of body fluids, prevent heat loss, etc.

[0003] The patent with the publication number CN218291404U discloses a cutting device for the production of carbon fiber composite dressings, including a storage component, the storage component including a workbench, a storage box, a rectangular hole, a connecting plate, a connecting column, a support plate, a cutting knife, a trapezoidal block, an electric push rod, a ball bearing, and a fixing rod; two storage boxes are arranged on the workbench, and rectangular holes are opened on the inner walls of both sides of the storage box, and a connecting plate is slidably connected to the rectangular hole, and two connecting columns are fixedly installed on the top of the connecting plate. After the utility model cuts the carbon fiber composite blank, the electric push rod drives the ball bearing to gradually relax the extrusion of the trapezoidal block, so that the spring drives the connecting plate to reset, and the connecting plate drives the supporting plate to move through the connecting column, and then the supporting plate drives the cutting knife to move into the corresponding storage box, so as to avoid accidental injury to the hand when arranging the carbon fiber composite blank after the work is completed, and thus avoid safety hazards.

[0004] Although the device has many beneficial effects, the following problems still exist during use: when the dressing is produced and supplied, it is usually provided in the form of large rolls for the convenience of transportation and storage. However, medical institutions usually use small rolls. The process of converting large-volume dressings into small-volume rolls requires cutting. During the cutting process, the existing technology can only cut it at a fixed size once, and cannot be adjusted according to the actual required size, which reduces the flexibility of the cutting process.

[0036] Furthermore, the anti-sticking component includes an upper rotating shaft 5, an upper rotating wheel 6, a lower rotating wheel 14, a lower rotating shaft 15 and a coating block 22. The bottoms of the multiple clamping rings 24 are fixedly installed with coating blocks 22.

[0042] Working principle: When the staff needs to use the anti-adhesion dressing shearing device, a large volume of dressing roll is placed between two symmetrically distributed bearing seats 4, and the clamping ring 24 is slid along the second connecting shaft 23 to engage with the corresponding limit block 21. The shearing blade 16 is located between two adjacent clamping rings 24. As needed, the position of the fastening ring 17 can be fixed and adjusted by inserting the limit column 20 into the limit hole 19 at different positions on the first connecting shaft 18, so that the winding roller 13 is clamped and fixed between the two The position of the winding roller 13 is adjusted so as to collect the cut dressing, and the driving motor 3 is started. The output end of the driving motor 3 drives the first sprocket 8 to rotate. The first sprocket 8 drives the second sprocket 11 and the first gear 10 to rotate through the transmission chain 9. The first gear 10 is meshed with the second gear 12, so the second gear 12 also rotates accordingly. Since the first gear 10 is fixedly connected to the lower rotating shaft 15, and the second gear 12 is fixedly connected to the second connecting shaft 23, the lower rotating shaft 15 and the second connecting shaft 23 also start to rotate. The rotating shaft 15 drives the lower rotating wheel 14 thereon to rotate. When the large volume of rolled dressing contacts the lower rotating wheel 14, it can drive the multiple upper rotating wheels 6 on the upper rotating shaft 5 to rotate. These rotating wheels are all provided with a polytetrafluoroethylene anti-stick coating to prevent the dressing from sticking during the cutting process. The rotation of the second connecting shaft 23 drives the shear blade 16 to shear the dressing. The dressing is clamped in the gap between the upper rotating wheel 6 and the lower rotating wheel 14 and is cut by the up and down movement of the shear blade 16. The cut dressing segment is passed through the pressing roller 7 on the support frame. Press lightly to ensure neatness, start the drive motor 25, thereby driving the first connecting shaft 18 to rotate, and further driving the multiple winding rollers 13 to rotate, so that the cut dressing segments are collected on the winding rollers 13. By adjusting the position of the winding rollers 13, the collection method of the dressing segments can be controlled. The coating block 22 is movably connected to the shear blade 16 to ensure that the dressing is always in contact with the anti-stick coating during the movement of the blade. The protective cover 2 ensures safety during operation and prevents direct contact between the operator and moving parts.
